Abstract:
A novel tobacco-curing system with a solar-assisted heat pump was proposed. The proposed system has various advantages, such as reducing energy consumption and pollutant emissions and enhancing the stability of system operation. The thermal characteristics of the system under different climate conditions were analyzed, and the economic and environmental benefits of different tobacco-curing technologies were compared. Results indicated that the dehydration rate, the mass flux of exhaust air, and the heat load of the novel tobacco-curing system in different months had similar changes with the baking time, and all reached the maximum in the later stage of color fixing. Compared with the power saving rate of a heat pump tobacco-curing system, that of the novel system reached 25.9%-35.1%. The dry leaf curing cost of the novel system was only 0.86-1.06 yuan/kg, which can reduce the cost by more than 60% compared with traditional coal-burning tobacco-curing systems in China. Compared with other parts of the tobacco leaf, the top leaf had the lowest dry leaf curing cost due to its highest mass of dry leaf. The payback period and the annual CO2 emission reduction of the novel system were 3.0-3.7 a and 15 586 kg, respectively.
为了寻求烤烟工艺过程中节能减排的有效途径并提高烤烟系统运行的稳定性, 设计了一种新型太阳能耦合热泵烤烟系统, 并对该烤烟系统的热力特性、经济效益和环境效益进行了分析.结果表明, 不同月份下该烤烟系统的失水速率、排湿风量以及热负荷随烘烤时间具有相似的变化规律, 均在定色后期达到最大值.与普通热泵烤烟系统相比, 新型烤烟系统的节电率达到25.9%~35.1%.与燃煤烤烟系统相比, 新型烤烟系统烘烤1 kg干烟成本仅为0.86~1.06元, 节约烘烤成本60%以上.由于上部叶的干烟质量相对较高, 与其他部位烟叶相比, 上部叶具有最低的干烟烘烤成本.此外, 该新型烤烟系统的投资回收年限为3.0~3.7 a, 并且每年的CO2减排量达15 586 kg.
